PIERRE DANSEREAU, OF MONTREAL, CANADA.

VEH ICLE-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 492,146, dated February21, 1893.

Application filed September 9, 1892. Serial Nor445,462. (No model.)

To all whom it may concern:

Be it known that I, PIERRE DANSEREAU, a subject of the Queen of GreatBritain, residing in the city and district of Montreal and Province ofQuebec, Canada, have invented certain new and usefullmprovernents inAxle- Skeins; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention has reference to a new method for securing the skein inposition and consists in two nuts on to one of which the skein isscrewed and the other is screwed on the journal and butts against theformer so as tOahOld it in position, the whole as explained hereinafter.

The object of my invention is to provide an easy running axle that willkeep its oil.

Referring to the drawings similar letters refer to similar partsthroughout the several views.

Figure 1 is a side elevation shown half in section of my invention. Fig.2 is also a side View shown half in section of my invention showing adifference in form. Fig. 3 is a front view of one of the nuts.

A is the skein proper which is provided with threads at B, while 0 isthe journal provided with threads at D and the ordinary sand band E. Theend F of the axle skein A is provided with a screwed cover G having awasher H inserted between it and the skein A so that no oil can leakout. This cover G is made so as to leave a space between it and the endI of the journal 0 which serves as an oil reservoir J. The journal 0 isprovided with the ordinary oil grooves K and L.

Now to secure the skein A in position onto the journal 0, I first put onthe nut M which can be made in section either as shown in Fig. 1 or Fig.2, only in the latter case I make an annular oil reservoirN into which Iintroduce the oil through the hole n closed by the set screw m, the onlydifference between the two forms being that to screw on or off the axleon the one shown in Fig. l a pin is inserted into the hole 0, the sandband E being cut away at P for this purpose and then simply unscrewingor screwing on the skein A, while in the one shown in Fig. 2 the sandband E is not cut away but the portion Q (Fig. 1) is made wider andhigher so as to come flush with the portion a of the skein A and heremake its surface either of flat sides or round so as touse a spannerwrench to screw on or ofi the skein A. The sand band E could of coursebe entirely dispensed with as shown in Fig. 2 the same band E being hereshown in dotted lines. After the nut M is in position I then screw on tothe journal 0 the nut R the journal 0 being provided with the threads 0for this purpose and when it is snug up I introduce the key S which fitsinto any one of the slots T, in the nut R,which happens to be oppositethe slot V on the journal 0, this key S being kept from coming out by ittouching the shoulder a of the skein A. This being done the skein A isthen screwed on.

The washers X and Yserve to take up any lost motion and the one X alsoserves to keep in the oil and keep out the dust. Any wear on thesewashers X and Y can be instantly taken up by simply taking off the skeinA, taking out the key S and then screwing up the nut R of the requiredamount and then inserting the key S in the required notch again.

Having described. my invention, what I claim, and desire to secure byLetters Patent, is-

In an axle skein,the combination, with the axle provided with thescrewthreaded portion 0, of the nut M, the washers X and Y one on eachside of the said nut, the nut R engaging with the screwthreaded portion0 and provided with a key for securing it in position, the skein screwedonto the nut M and having a shoulder 0. adapted to bear against the endof the said key, and a hollow cap secured to the free end of the skeinand inclosing the end of the axle bearing, substantially as and for thepurpose set forth.

In testimony whereof I have affixed my signature in presence of twowitnesses.
